Identifying and Avoiding GM Sweet Corn Seed in Canada
Consumers are increasingly asking growers and grocery stores in Canada not to sell GM (genetically modified, also called genetically engineered) sweet corn. In response to questions from vegetable growers who want to confirm the information they use to avoid planting GM sweet corn seeds, the Canadian Biotechnology Action Network (CBAN) has compiled the following information.
There are no GM vegetables grown in Canada except for GM sweet corn, and GM sweet corn is not prominently advertised to smaller growers. Because of this, some vegetable growers are not familiar with common GM seed identifiers that grain and oilseed growers frequently see in seed catalogues.
To our knowledge, Canadian seed catalogues that service smaller seed buyers (purchasing less than 25,000 seeds) are not currently selling GM sweet corn seeds (if you find GM sweet corn in any catalogues please contact CBAN).
- A number of seed companies in Canada and the US have signed the non-GM Safe Seed Pledge:“For the benefit of all farmers, gardeners and consumers who want an alternative, we pledge that we do not knowingly buy or sell genetically engineered seeds or plants.” Click here for a list of participating companies.
- Some major seed houses such as Stokes do not sell any GM seed and prominently display a non-GMO logo.
- US based vegetable seed distributors Siegers, Rupp and Seedway are selling GM sweet corn varieties.
- In Quebec, the company La Coop Uniforce sells a few GM varieties (2013/2014).
- There are two companies producing GM sweet corn seed – Seminis (owned by Monsanto) and Syngenta – and these are generally sold through seed catalogues and by other seed distributors.
Indicators of GM Seed
- Key terms: GE, genetically engineered, GM, genetically modified. E.g. Seedway’s 2015 catalogue names “GE” varieties, but not all catalogues label GE/GM.
- Colour cannot be used to help avoid GM seed because there are GM sweet corn varieties in each colour.
- Purchasing GM varieties requires farmers to sign a stewardship agreement and/or get a license number.
- GM sweet corn seeds advertise two GM traits: “insect protection” (above and/or below ground) and tolerance to the brand name herbicides “Roundup” and/or “Liberty”. Two companies produce GM sweet corn seed: Seminis (owned by Monsanto) sells “Performance Series” and Syngenta sells “Attribute” and “Attribute II”.
